Description

(54) RAW MATERIAL MIXTURES FOR MANUFACTURING The invention relates to the production of heat and sound insulation materials and can be used in the construction as heat and sound insulation material. The known raw material mixture for the manufacture of foam silicate products, including fly ash, liquid glass, aluminum powder, and activator of hardness ij. The disadvantage of this mixture is the high expansion temperature, which complicates the process of structure formation, as a result of which the material is heterogeneous with a large pore structure. Closest to the proposed technical essence raw mix for the production of foam silicate products f2}, including wt.%: Liquid glass 30-37 Alc 4I niVa powder 1-3 Sodium fluoride fluoride EthylHydroSiloxane liquid 1-3 Oleic acid 1-4 Ash-and-OilOthers The disadvantages of this mixture are it is necessary to heat it up, the use of high-density LCD-PEN-SILICATE PRODUCTS of glass, which complicates the production technology, - low thermal insulation properties. The purpose of the invention is to reduce the thermal conductivity of the raw mix and the cost of products, obtaining it in natural conditions at. The goal is achieved by the fact that the raw material mixture for the manufacture of foam silicate products, including liquid glass, sodium silicofluoride, blowing agent, fly ash and water, contains household soap in the following ratio of components, wt.% Liquid glass 45.9-59, 6 Creme Sodium fluoride9.47-11.6 O household soap, 15-0.1V Fly ash22.9-36.4 Water5.8-8.0 Foam concrete manufacturing technology is as follows. Liquid glass with a density of 1.25-1.45 and sodium silicofluoride in the specified proportions are tilted in the mortar compartment of the foam concrete mixer (laboratory or industrial) for 2-4 minutes, then the ash is poured and the mixture is stirred to obtain

homogeneous mass within 7-10 minutes At the same time, a soap pacTBOD with a soap ratio is knocked down in a foam booster; : water 1: (35-4 pX) Mix the mixture for 3-4 minutes, then pour it into molds. The mixture hardens under natural conditions. (10-30 ° C) ..

Depending on the production conditions. Mixture after a delay of 4-6 hours: it can be subjected to autoclave treatment at an overpressure of up to 12 atm, or drying at 50-80 s, which extends its range of application, for example, in the production of 2- or 3-gels. products based on a variety of dense materials on single-stage technology.

In table 1 given the composition of the components of the raw mix.

Table 2 shows the physico-mechanical parameters of the compositions.

The proposed mixture has an available and uncomplicated manufacturing process. At the same time, the proposed mixture makes: a reduction in the cost of production due to affordable and cheap components, the possibility of obtaining products of large sizes due to the low

shrinkage, which is achieved by creating foam mixture in natural conditions, the possibility of using the material in the production of 2- or 3-layer products in any thermal and moisture conditions.
